Memoranda of the Canadian Grain Commission
Trade memos
Trade memos are issued under the general authority granted to the Canadian Grain Commission by p.118 (h) of the Canada Grain Act, as well as other specific provisions of the Act. They are effective from their issue date until the end of a given crop year, at which point they are reviewed and may be re-issued.
We issue memos to provide:
- general information
- information required to satisfy Canadian Grain Commission orders or regulations
- information about our procedures
Memos might include information such as:
- grading instructions
- requirements to obtain special permission, such as permission to store grain on the ground
